TYPEWRI'IING MACHINE.

Application filed. June 25, 1928. Serial No. 647,501.

To all whom it may concern:

Be it known that I, BURNIIAM C. STICK- NEY, a citizen of the United States, residing in Rutherford, in the county of Bergen and State of New Jersey, formerly of Elizabeth. New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

The invention relates to a machine for typing upon paper work-webs, comprising several plies, either fan-folded or unattached to each other, and upon each of which plies arcusually printed a succession of forms; the form lengths or sections of one ply registering with those of the other plies. and carbons being interleaved with the plies.

The work-webs may be continuous, or of indefinite length, according to the number of forms which compose the'same. Ordinarily, however, or at least until so worn as to call for replacement, a fixed length of carbon-sheet is employed; the carbons being shifted, relatively to the work-webs from one form-length to the next succeeding form-length of work-webs when the typing of a form is completed. The usual practice has been; after typing of a form, first, to lift the platen bodily to release the web therefrom and to release the carbons for their shift; then to shift, one formlength rearward, a. carbon-carrier with the carbons attached thereto, while holding the work-webs; and then to reset the composite web for commencement of typing on the next form and to replace the platen.

In the co-pending application of Jesse A. B. Smith, Serial No. 640,315, filed May 21, 1923, there is described a machine, operating according to a somewhat different method, for obtaining the same results, and which has certain advantages as to lightness, simplicity and expeditiousness in its manipulation. In this Smith machine, neither the platen nor a carbon-carrier nee be shifted in the carbon-shifting operation. The carbons are anchored at their rear, and sufiicient slack is provided the composite web between the platen and the anchorage of the carbons to permit writing of a form before such slack is entirely taken up by the line-spacing movements of the platen. After completion'of a form, the Smith procedure is: first, to reverse the platen until.

the carbons are clear thereof and are loose in the work-webs; a slack in the carbons and work-webs being thus re-established between the platen and the carbon anchorage;

then, to rock against the composite web an form-length, with the slack therein, originally provided.

The present invention relates more particularly to a machineof the general class of the aforesaid Smith machine, in that the platen need not be shifted as an incident to the carbon'shifting operation, and in that means, such for instance as a rockable arouate table, is employed to take up a slack in the web which is first established to permit line-space .feed of the web without pull on the carbon-carrier in the typing of a form, and which is reestablished in the act of re t-racting the Web to free the carbons from the platen preliminary to the form-to-form shift of the samev relative to the work-webs. The present invention, however, is primarily distinguished from the aforesaid Smith structure in that the carbon-carrier is not simply a stationary anchor for the carbons, but is movable to serve as the means by which the form-to-form shift of the carbons is actually efiected.

An object of the present invention is the provision of means whereby the carbon-carrier may be retracted (after elimination of the aforesaid ire-established slack in the web), to efi'ect the fo-rm-to-form shift of the carbons along the web, thus rendering unnecessary forward advance of the web by rotation of the platen, or otherwise, for effecting such form-to-form shift; and making possible a reduction of the required number of advances of the web, or platen,

to the single advance involved in positioning the compositeweb for commencement of typing on a form after the form-to-form shift of the carbons has been effected. In this connection, a feature of the invention is the avoidance of the necessity for any gage to determine by eye the correct amount of relative shift of the carbons and work-webs, such for instance as a gage to which the leading end of the work-Webs has heretofore been fed by the platen; thus relieving the operator of considerable care.

A further feature of the invention is a mounting of the arcuate table, or equivalent device, and of the carbon-carrier, such that the same may be supported independently of each other, and be movable independently of each other, in a manner best to coordinate their several actions on the web in a simple and compact structure.

A further feature of the invention is the provision of a novel and simple operating and locking means for a clam device to hold the work-webs against displacement while the arcuate table, or its equivalent, acts on the web to remove the slack re established therein in freeing the carbons from the platen.

A further feature of the invention is the. mounting of the arcuate table or equivalent device, between the platen and the carboncarrier so that its further upward movement, after taking up slack in work-webs, will advance the paper from the rolls or folds, and its downward return will leave the slack in the work-webs in position between the carbon-carrier and the platen, ready for linefeed to the platen as the work proceeds.

Other features and advantages will hereinafter appear.

in the accompanying drawings.

Figure 1 is aview, in side elevation, of the platen-carriage and connected parts, embodying certain features of the present in vention; the parts being in position for commencement of writing on a form.

Figure 2 is a view similar to Figure l, with the additional showing of other parts, embodying features of the invention, the composite web being shown as fed rearward, after completion of typing on a form, to clear the carbons from the platen preliminary to the operation of eflecting the formto-form shift of the carbons relative to the work-plies.

Figure 3 is a View, in side elevation, of the apparatus shown in Figure 2; the websupportingtable being shown as lifted to take up the slack in the web after the web has been retracted to Figure 2 position.

Figure 4 is a view similar to Figure 3, ex-

, cept that the carbon-carrier has been thrown down to efi'ect the form-to-form shift of the carbons relative to the work-webs.

Figure 5 is a top plan View of the appara-' prising ends 12 and a rear paper-shelf 13.

The. us al releasable teed-rolls i4 ran, on the under side of the platen. The platen-frame is mounted upon a carriage 15, for move ment in letter-feed and return directions up on a rail 16. The platen may be rotated by knobs 17 on the axle 18 thereof, or by means of the ordinary line-space mechanism, comprising a line-space wheel 20.

The work-web, usually comprising superposed plies 19 (which may be loose plies or which may be a fan-fold), is drawn up from a supply-spool, or from a zigzag folded pile. (not shown), but which may be contained in a receptacle arranged in the rear of the typewriting machine and its stand 21. As the plies of the work-web rise from the sup ply at 22, they first pass through a carbonearrier. The carbon-carrier is in the form of a bail comprising arms 23, fast on a rockshaft 24, journaled in plates of a standard or frame, securedto a platen-carriage, and movable with the latter in letter-feed and return directions. The plates 25, one at each side of the frame, are connected by a cross bar or tie 26, at the center of which there is an ear 27, having journaled thereon a roller 28 supporting the frame on a rail 29. The rail 29, along which the frame moves with the platen-carriage, is supported by brackets 31 on the rear of the machine-frame 32. Attachment of the carrier-frame to the platencarriage is by means of ears 33, one formed on each of the side plates 25, and which are offset at 34, toward each other, to form flanges which are secured by screws 35 to brackets or arms 36, in turn, secured at 37 to the usual rear cross piece or tie38, which forms part of the carriage 15.

The arms 23 of the carbon-carrier are connected at their distal ends by a cross-' piece 39. At each end of the cross-piece is a block 40; and secured to each of the blocks 40 is a carbon-carrier-blade 41. The blades 41 are shown as projecting from the blocks 40 between the plies of the work-webs; and the blocks 40 are either stepped or provided with spacing-pieces, so that the blades may be suitably spaced apart for free movement of the work-webs between the carbons. A. connecting piece or guard-plate 42 is set over screws 43 on the blocks, and is held down on the latter by thumb-nuts 44. As shown in the drawings, the carbons 45 are secured at their rear ends to the blades 41, and thence extend forward with the workwebs.

The normal or typing position of the carhon-carrier is that shown in Figure 2. It I is thrown to this position and held in this rteaeee appropriate time, as hereinafter more fully to be explained, the carbon-carrier is thrown from its Figures 1 and 2 position to its Figure 4 position. This throw of the carbon-carrier is effected by means of a bell-crank-lei'er l8, pivoted at 49, on the lefthand carrier-frame plate 25, and having on the end of its upper arm 50 a handle 51 for operating the same. The lower arm 52 of the bell-crank is slotted at 53 to engage a pin 54 on an arm 55, which forms, with the left-hand carrier-arm 23, a bell-crank. A stop-pin 56' on the car 33 of the left-hand carrier-frame plate serves as an abutment for the bell-crank, ca1'bon-carrieroperating lever 48, to determine the normal or typing position of the latter, and, through the connections 53 and 54, to determine the normal position in which the carbon-can rier is held by the spring l6.

The work-webs, on passing through the carbon-carrier, in interleavement with the "typing gripped by the feed-rolls 1a to the platen,

carbons, fall in the form of a loop or slack 57, just forward of the carbon-carrier, and between the latter and a web-supporting table 58; that is to say, when the parts are in the Figure 1 position for typing. In the operation, the composite web,

as shown in Figure 1, is given a line-space feed over the table 58, down over the curved forward upper end 59 thereof, down over the paper-table13 on the platen-carriage, under and around the platen to the printing line, and thenceupward across the front of a plate or table 60, and along a stafi 61, which isriveted at 62 to the rear of the plate 60, and which carries an adjustable gage 63, to which the leading edges of the work-plies are fed, by forward rotary movement of the platen,.to determine the correct position of the web for commencement of typing on a form. It will be noted, Figure 1, that two form-lengths 64 and 65 are shown in advanceof the form-length 66, on which typ-' ing is to be effected.. After positioning the weblby means of the leadingends of the form-section 64, such form-section may, however, be severed from therest of the web by means of a knife-blade 67, as indicated in Figure 1, preliminary to commencement of typing on the form-section 66. As the formly, without pull of the carbons on 41 of the carbon-carrier.

section 66 is line-spaced upward in the typing operation, the slack 57 is taken up. It will be understood, however, that the-slack 57 is sufficient not only to permit the web to be advanced from Figure2 to Figure 1 position, but also to permit completion of typing on the form-section 66, without completely taking up the slack, and, consequentthe blades,

The typing-on aform having been comple'ted, the platenis tnined'in reverse direction by one of the hand-knobs-1 7"until, as

indicated in Figure 2, the carbons are clear of the platen. This position of the web may be indicated by registration of the leading ends of the form-section with a second gage 68, adjustably set onthe stafl 61.

The next step is to clamp the form-section 65 of the work-webs to the front of-the plate 60, so that, as presently to be described, the carbons may be shifted rearward with respect to the work-webs without rearward displacement of the latter. The plate 60 is secured to, and may be unitary with, brackets 69, held byscrews to the tops of the side plates 12 of the platen-frame. The plate 60, which is cut away centrally at 71, as indicated in Figure 5, to expose the gage 68, also has its side portions slotted at 72, to

receive screws 73, by means of which the knife-blade 67 is adjustably set thereon. lit will be understood that the adjustments of the gages 63 and 68 and of the knife-blade 67 are for setting the apparatus for use sists ofa clamping bar 74, which isprovided with a non-slip covering 75, and which is supported on ia pair of arms 76 on a rockshaft 77, journaled in brackets or plates 78, secured to the brackets 69. A. spring 7 9, attached to a pin 80 on the right-hand clampbar-arm 76, and to a pin 81 on the righthand bracket 69, normally holds the clamping bar in Figure 2 position, and returns the same to Figure 2 position when free to do so clamp the work-webs, there is pivoted at 82, to the right-hand plate 78, an arm83 having an operating handle 84 on the end thereof. The other end,of the-arm 83 is cam-shaped, as indicated at 85, so that, when the arm 83 is thrown flirward, the cam 85 The normal position of the clamp-arm 76,

and, consequently, of the clamp-bar74, is determined. by engagement of the righthand clamp-armq76'with the clamp-operat ing arm 83 and its cam-shaped end 85,:15

shown in Figure 2. l Tn turning back the platen to free the car'- For throwing the bar to the plate 60 to bons therefrom, slack 57 is ire-established in the web. In order that thecarbons may be smoothly shifted rearward along the web-' plies, it is desirable that this slack be eliminated. For this purpose, the table .58, which has a paper-guiding surfaceof long curva ture, is made fast to a rock-shaft 88, journaled in the turned-over upper ends of the .brackets 36, so that the table 58 may be swung up from Figure 2 to Figure 3 position For thus swinging up the table 58, one of the side plates or ribs 89 thereof has attached thereto, at 90, an arm 91 having av handle 92 thereon. This handle is drawn forward, as indicated in Figure 3, to lift the table. A coil-spring 93 on the rock- 'shaft 88, having one end fast to one of the brackets 36,1an d the other end made fast to a collar 94'ion the rock-shaft, actsto partly counterbalance the weight of the table 58, so as to facilitate the lifting operation. A

stop-pin 95 on the, right-hand side plate 89 of the table 58,"by engagement. with an offset 96 (see Figure 3) on an arm 97, forming part of the right-hand'side plate 25 of the standard for the carbon-carrier, determines the upper, Figure 3, position of the table 58. It will be noted (see Figure '3) that, when the table 58 is in its upper position, the slack 57 intheweb has been eliminated.

The carbon-carrier is now thrown down from Figure? to Figure 4 position, in a manner already indicated, by a'forward pull on the handle 51; and,,in moving downward to Figure 4 position, draws the carbons back a form-length along the work-webs, as indicated in the difference in position of the leading ends of the carbons, observable uponrefereFc'e to Figures ,3 and 4.' The curvature of the table 58 being-3a long one, binding of the carbons on'the work-webs does not take place when the caribou-carrier exerts this downward pull'onthe carbons. For determining the extent of shift ofthe carbons rearward along the work-plies, the right-hand plate 25 of the carbon-carrier standard has a rearward offset 98, at the end of which are a series ofpin-holes 99,,

into a selected one of which a stop-pin 100 is inserted. This pin liesin the path of downward movement of the corresponding carrier-arm 23, and arrests the carbon5carrier after a movement thereof equal to one 'form-length'of the work-webs. Since 'workwebs of different form-lengths may be used in the machine, theextent of movement of the carbon-carrier maybe varied accordmg- 1y, by changing the setting of the pin 100 from one to another of the holes .99.

After the shift of the'carbons has been effected, the handles 51 and 92 are released,

so that the table 58 ma drop to Figure2 position by gravity, an s the carbon-carrier be thrown up to Figurev 2 position by the spring 16. The clamp-locking arm 83 is meat-es then thrown from Figure 3 to Figure 2 position, releasing the work-webs. The platen is now given a forward rotation to bring the leading edges of the leading typed form-section to the gage 63, as indicated'in Figure 1; thus positloningthe web for commencement of typing on the first untyped form-section, also as indicated in Figure 1'; and the leading typedzform-section is then severed as hereinbefore indicated.

Variations may be resorted to within'the scope of the invention, and portionsof the improvements may be used without others.
